Toa Maru, Japanese transport vessel wreck near Gizo, Solomon Islands
The Toa Maru is a Japanese transport vessel lying on its side on the seabed near Gizo, in the Solomon Islands. The wreck spans several cargo holds and offers multiple entry points at different depths.
The ship was sunk in 1943 by an American submarine while carrying supplies across the Pacific. It had been part of Japan's wartime logistics network, moving equipment and materials to support operations in the region.
The wreck still holds original wartime cargo in its holds, including military equipment and supply goods that have remained largely untouched. Divers who pass through these spaces often describe a quiet, sobering feeling that is hard to find elsewhere.
The site is best suited to experienced divers, as some sections go quite deep and the structure can be disorienting inside. Currents in the area can shift, so checking conditions before entering the water is a good habit.
Among the cargo still resting in the holds are tanks and thousands of cement bags from the ship's last voyage, which have hardened over the decades into solid blocks. This makes some sections of the wreck look more like a stone cave than a ship's interior.
